中文摘要：
以孔雀河流域典型地带为研究区域,利用电磁感应式大地电导率快速测定技术探测获得表观土壤电导率数据,构建了基于电磁感应技术的区域尺度剖面分层土壤盐分精确解译模型,精准解译出研究区剖面土壤盐分含量信息,并以此为数据源采用三维普通克里格法解析并评估了研究区土壤盐分三维空间分布特征。研究表明,不同测量位数据的综合应用能够表征剖面土壤盐分信息,构建出的剖面分层土壤盐分解译模型具有较好的精度;研究区不同区位土壤盐分三维分布呈现明显差异;研究区土壤主体属中度以上盐渍化,局部地带属于重度以上盐渍化土壤,需采取有效治理措施对土壤盐渍化进行可靠防控。
英文摘要：
Taking typical area of the Peacock River Basin as the study area, apparent electrical conductivity of soil was induced by using electromagnetic technology, and thus layered soil salinity interpreting models were built up. 3-D soil salt distribution was characterized by using 3-D ordinary Kriging method. The profile soil salt information was presented by different operation modes. The layered salinity interpreting models showed good accuracy. Soil salt distributions of different zones in this area were significantly different. Most of soil in study area belonged to moderate salinity, and some local areas were severe saline soil. Thus, the effective countermeasures should be taken to prevent and control soil salinization in this region.
